callback<Function> - Return: Boolean
Send a message to a worker or master, optionally with a handle.

In a worker this sends a message to the master. It is identical to process.send().
This example will echo back all messages from the master:
1 2 3 4 5 6 7 8 9 | if (cluster.isMaster) { var worker = cluster.fork(); worker.send('hi there');} else if (cluster.isWorker) { process.on('message', (msg) => { process.send(msg); });} |
